Application filed February 23, 1923; Serial naeaasie.

The present invention relates to jar wrenches, the object being toprovide a structure that'will have an e itective gripping action on ajar cap or the like without distorting and injuring the cap, the deviceautomatically positioning itself so as to grip the cap around the; topmargin thereof where it is reenforced by the top wall ofthe cap. l V.

The preferred embodiment of the invention is illustrated in theaccompanying drawing, wherein j Figure 1 is 'a plan view of the wrenchin its closed position, 7

Fig. 2 is a similar view illustrating the same open,

Fig. 3 is a detailsectional view on line 3 8 of Fig. 1, and

Fig. 4 is a side elevation showing wrench in position on the cap of ajar.

In the embodiment disclosed a pair of levers 5 are provided that arepivotally cornected between their ends, as illustrated at 6, the arms ofthe levers at one side of the pivot constituting handles 7 the otherarms being preferably flattened and outwardly bowed to form jaw arms,designated 8.

The article-embracing jaws preferably semi-circular in form, are shownat 9, and are'pivoted together at their rear ends, the pivot beingdesignated 10, and this pivot passing through one of the handle arms 7,as illustrated in Figure 3., A washer 11 may be interposed between thepivoted ends or" the jaws 9 and said handle arm. The free ends of thejaws 9 are pivotally connected as shown at 12 to the free ends of thejaw arms 8, and said aw arms 8 are adapted to abut against each otherwhen the wrench is in its closed position, as illustrated in Figure 1,in which position thehandles 7 are preferably in substantially parallelrelation. The inner sides oiithe jaws 9 are serrated, each havingoppositely disposed sets of teeth 13 and 14.

Sufficient play is permitted between the the the.

pivotal connections and the jaws and levers have sufficient resiliencyto allow the ring formed by the jaws 9 to be opened to a con side'rableextent, as indicated in Figure 2.

Therefore when 'opened the jaws can be placed around't-he upper rim of ajar cap, as15 in Fig. 1. WVhen so positioned the pivotal portions of thelevers, which extend across the rin constitute a stop or support thatwill rest upon the top wall of thecap and preventthe jaws passingdownwardly too far'over the cap. By removing the handles to parallelrelation obviously the jaws will be drawn towards each other and lengaged with the cap. The opposite set teeth 13 and 14C constitutegripping means that-will insure the rotation of the cap with the wrenchin either of opposite directions.

Inasmuch therefore as a powerful gripe CLYDE a. .Ivrrr'ran, or vrnernre,I assass nsping action can be obtained with a good leverage: "forturning, it will be evident that caps may bescrewed'tightly to place orremoved from a jar without difiiculty and because of the relation andmounting of the article-engaging jaws the levers are made to alsoperform the function of a positioning device, so that said jaws willengage the upper margins of the cap, which being reenforced by the topwall of such cap, will not be'readily deformed.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled inthe art, with out further description, and it will beunderstood that various changes in the size,

proportion and minor details of conshape,

struction, may beresorted to without departing from the spirit orsacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is I r 1. A jar wrench, comprisingcrossed le-' vers plvotally connected between thelr ends,

and article-embracing clamping jaws having their ends pivotallyconnected to the corresponding ends of the levers and extendingrearwardly beyond the pivotal connection between the levers, said leverseXtend- I ing across the space-between the jaws.

2. A ar wrench, comprising crossed levers pivotally connected betweentheir ends and having arms on one side of the pivot that are bowed andadapted to abut at their free ends, and article-embracin clamping jawspivoted to the said free ends of the lever armsand being of greaterdiameter than the bowed portions of the levers.

V 3. A jar Wrench, comprising crossed levers pivotally connected, andart1cle-embracing' jaws pivotally connected together and having suchpivotal connection mounted on one of the levers, said jaws and leversbeing also connected at points spaced from said pivotal connections, andsaid levers extending across the space between the jaws and at one sideof said jaws. 7 I
